METALLIC' SHINGLE.

Specification of Letters Patent.

Application filed July 5, 1910. Serial No. 570,264.

stood from the following description taken in connection with theaccompanying drawing in which Figure 1 is a face view of a shingle, ofgenerally square outline, embodying my im- 'provements: Fig. 2 a numberof the shin-- gles, properly assembled: Fig. 3 a face view of the sheet,cut to pattern, and ready for certain edge bendings to form the completeshmgle: Fig. 4 a vertical seetlon through the upper tab: and Fig. 5 aface view of the improved shingle when modified in outline form, ascompared with the other figures, being diamond-shaped.

The various figures of the drawing exhibit some diversity of scale.

In the drawing :1, in Fig. 3, indicates the flat plate, cutto pattern,substantially square in outline: 2, the lower let'thand edge of theplate: 3, the lower right-hand 5 edge: 4, the upper right and left-handedges: 5, a. tab at the left-hand corner of the plate, forn'ied bynotching the plate, as shown, the tab projecting diagonally upward,parallel with edge 2 and as far as up- 4 per left hand edge 4: 6, asimilar tab at the right-hand corner of the plate: 7, a tab projectingfrom the top corner of the plate and formed by notching the plate. theupper extremities of this tab being in the lines of prolongations of theedges 4 of the plate: 8, a dam across the foot of top tab 7 and formedby so indenting the back of the plate as to throw upward from the faceof the plate a ridge having a length equal to tab 7: 9, the main body ofthe plate: 10. a booking flange extending along below the lowerright-hand edge of the shingle, this hook being formed by bending theportion 3 of the blank under and inwardly, but not so close up to thebody as to prevent a hooklower left-hand edge of the shingle, and

formed by turning under edge 2 of the blank: 12, the cut away lowercorner of the blank to prevent the oi'erlappin of the contiguous ends ofthe hooking flhnges 10 and 11: 13, a hooking flange at the upper left-.hand corner of the shingle, formed by turning the upper left-hand edge4 of the blank over onto the body: and 14, a similar hooking flange atthe upper right-hand edge of the shingle, formed by turning the upperright-hand edge of the blank over onto the body.

In assembling the shingles on the roof, a shingle, disposed as in Fig.1, may be secured by a nail at tab 7 and a nail at tab 6, these tabsbeing preferably punched for the nails. It is to be observed that allthe tabs project out from the body of the shingle and not from thehooking flanges, this con-- struetion permitting of the upper portion ofthe shingle lying closely down to the roof.

Assume the shingle thus referred to to be the lower one seen in Fig. 2.A second shingle is now to have its hooking flange 10' hooked under theflange 13 of the first shingle, the tab 6 of the second shingle crossingthe dam of the first shingle and projecting beyond the side of tab 7 ofthe first shingle, tab 6 of the second shingle is then to be nailed.This would constitute the lefthand shingle of Fig. 2. The third shingleis then to have its flange 11 hooked onto flange 14 of the firstshingle, its lower corner covering the nailed tab (5 of the firstshingle,

and the tab 5 of the third shingleoverlying the body and entering underflange 14; of the second shingle, the body of the third shingleoverlying the nailed tab 6 of the second shingle, and so on over theentire roof, it being understood, of course, that in finishing out theedges of the roof half shingles will be employed, as is usual inmetallic shingle work. Side tabs 5 and 6 are alike, in fact the shinglesare entirely symmetrical and it follows that the laying of the shinglesmay be to the right or to the left, as is most convenient, and that oneof tabs 5 or 6 will be nailed which comes into direct contact with theroot' as distinguished from an overlying tab. In the manner of layingwhich has been described, and as is indicated in Fig. 2, the right-handtabs 6 will be the nailed ones asthey come directly against the roof,while tabs 5 are overlying tabs.

It is to be observed that, as will be seen by reference to Fig. 3, thewastes from an original rectangular plate are but trifling. It will befurther observed that the main body of the shingle at its upper portionmay lay close to the roof and that the nailing tabs come down close tothe roof, being projections from the bodyitself; and that nailed point-sare well housed so that leakage cannot occur at tabs 5 and 6 and that,furthermore, dam 8 prevents water being blown upward to tab 7. I

The improved shingles not only provide a roof of superior quality as totightness, but they lend themselves to very economical con- "structionowing to smallness of Waste and to the fact that they are produceablefrom a flat plate at a single operation of a combined stamping andbending machine.

1. A metallic "shingle comprising, a rectangular body, overturnedhooking flanges at the upper edges of the body, underturned hookingflanges at the lower edges of the body, tabs formed-by upwardprolongations of the lower edges as the body beyond the upper edges ofthe body, a tab formed by 2. A shingle comprising a sheet metal I,

body having underturned edges on two ad'- jacent sides and overturnededges on the other two adjacent sides, the last named edges beingcutaway at their meeting corner to accommodate a tile to be superposed, aconvexdam being formed in the corner of saidtile between said overturnededges.

3. A roofing tile formed of sheet metal having underturnedlocking edgeson two adjacent sides and having overturned locking edges on the othertwo adjacent sides, said overturned edges being cut away to leave aspace at their meeting corner, the tile being'provided with a nailingtab extending from said corner, an outwardly convex dam being alsoprovided-across said corner between said overturned flanges.
